As this reworked competition gearbox meshed with the bi-turbo M158 6.0-liter V12 from Mercedes-Benz AMG in Auto mode, feisty Sport mode or full-on Launch Control, I was amazed that I wasn't beaten up more.

The Huayra should do it with a target-launch rpm of 3500 rpm, says Galletti, possibly in second gear to take advantage of the AMG’s 738 pound-feet of torque and avoid the 1-2 upshift at 58 mph (second gear tops out at 75 mph at the 6000-rpm redline).

Not like a Huayra without a Track Pack should be kicked out of bed for eating crackers, with its SAE-rated 720 horsepower peaking at 5,800 rpm and 738 pound-feet of torque flat-lining from 2,250 up to 4,500 rpm.

The Huayra, says Pagani, is inspired by the idea of a roadgoing jet, and he's spent a lot of time tuning the turbocharged V-12's intake noise so it sounds like an F-15 spooling up when you get on the gas.
